We report a 2-year-old boy who was admitted with priapism with a history of the perineal trauma. Doppler ultrasonography revealed signs of high-flow priapism. Magnetic resonance imaging revealed an intrapelvic mass beside the root of the penis. The serum alpha-fetoProtein level was 54.600 ng/ml (Normal range: 0-9 ng/ml). Tru-cut biopsy was performed and endo-dermal sinus tumor was diagnosed. At the fourth day of chemotherapy, the penis became progressively less turgid and soft. After the first cycle chemotherapy, priapism had completely resolved.en10.4999/uhod.09028info:eu-repo/semantics/openAccessChildrenEndodermal sinus tumorPriapismArticle2114547Q4WOS:000289140000007Q4
